Power Supply Units from Foxconn and Hiper Group in Our Lab

Today we would like to introduce to you five new power supply units: two Foxconn and three more from Hiper Group. These PSU models range from 350W to 580W. So you should be able to find a solution for every budget in our new review.

Hon Hai Precision Industry, a major contract manufacturer of electronics (EMSNow ranks it second after Flextronics), has also been actively promoting its produce – mainboards, coolers, system cases and power supplies – under the Foxconn brand. In this review you are going to see two Foxconn WinFast power supplies that are meant for retails sales apart of a system case; PC cases come with other models of Foxconn PSUs which will hopefully be covered in our upcoming reviews.

The other PSUs to be reviewed today come from Hiper Group that manufactures and sells retail products only. Hiper Group does not make system cases, except for some rather narrowly targeted MicroATX models for home multimedia centers. The company currently offers six inexpensive PSUs ranging from 350 to 525W (I’m going to test the junior, 350W unit) and two more expensive models with up to 580W wattage.

Foxconn WinFast FA-380A and FA-550A

As I learned during my tests, these two models are absolutely identical in appearance and functionality as well as in circuit design, but they differ in the specified wattage and, accordingly, in the ratings of some of the components. I’m going to describe them both together.

These PSUs come in black cardboard boxes which are identical, save for the model name.

Their appearance is ordinary enough. The case is painted matte black and is cooled with one 120mm fan. The samples I actually tested could only work from a 220V AC source. You couldn’t switch them to any other input voltage.
